RuntimeException添加此库后，我的应用程序正在抛出一个。现在，例如其他帖子建议我必须Activity在我的Manifest. 我怎样才能用 BetterPickers 做到这一点？这是Manifest库中示例应用程序的文件，这是我的：

<?xml version="1.0" encoding="utf-8"?>


<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
     <!-- First item is for saving state while rotating -->
    <activity
        android:windowSoftInputMode="stateHidden|adjustNothing"
        android:configChanges="orientation|keyboardHidden|screenSize" 
        android:launchMode="singleTop"
        android:name="com.foodbuilder.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <!-- Searchable configuration -->
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>

        <meta-data android:name="android.app.searchable"
        android:resource="@xml/searchable" />
    </activity>
</application>

</manifest>

编辑：这是我的 LogCat

这就是我尝试过的：

<activity>
...
    <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="com.doomonafireball.betterpickers"/>
    </intent-filter>
</activity>

这是我添加库的方式：

在此处输入图像描述

这也是我的实现：

package com.foodbuilder;

import com.doomonafireball.betterpickers.numberpicker.NumberPickerBuilder;
import com.doomonafireball.betterpickers.numberpicker.NumberPickerDialogFragment;

public class MainActivity extends FragmentActivity implements TablesDialogFragment.NoticeDialogListener, NumberPickerDialogFragment.NumberPickerDialogHandler {

...
private NumberPickerBuilder numberPickerBuilder;
...
}

非常感谢！

我的天啊。经过两天与这个图书馆的斗争。我去了图书馆，properties -> Build Path -> Order and Export and "Unchecked" android-support-v4.jar.我什至不知道为什么要检查。
